Detailed Implementation

[0028] The core of this application is to provide a battery compartment box for a material transfer trolley to improve the convenience of battery replacement for the material transfer trolley.

[0029] Another key aspect of this application is to provide a material transfer cart having the aforementioned battery compartment for a material transfer cart.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1As shown, the battery of a traditional material handling trolley is usually located in the battery compartment 0100, and the cover 0200 of the battery compartment 0100 is fixed to the battery compartment 0100 with 6 symmetrically arranged bolts 0300. When the battery needs to be replaced, all 6 bolts 0300 need to be removed in sequence before the cover 0200 can be opened to replace the battery, which makes battery replacement of AGV material handling trolleys inconvenient.

[0032] Therefore, such as Figure 2 As shown in the figure, this application discloses a battery compartment box for a material transfer cart, including a box body 10 and a cover 20. The box body 10 can be opened or closed by sliding the cover 20 along a first direction of the box body 10 or rotating it around a rotation axis 21, so as to facilitate the replacement of the battery 200. Compared with the method of fixing the cover to the battery 200 compartment with bolts, the convenience and efficiency of replacing the battery 200 of the material transfer cart are improved.

[0033] The following will combine Figures 2 to 4 The battery compartment box for material transfer carts disclosed in the embodiments of this application will be explained and described in detail.

[0034] Among them, such as Figure 3 As shown, the box body 10 may have a receiving cavity 11 for accommodating the battery 200, and a conductive metal spring is provided in the receiving cavity 11. The metal spring abuts against the output end of the battery 200 to limit the battery 200 while conducting the current of the battery 200 to the output end of the box body 10, so that the output end of the box body 10 can be electrically connected to the body 300 of the material transfer trolley to provide a power source for the material transfer trolley.

[0035] like Figure 2 and Figure 4 As shown, the cover 20 can be placed over the opening of the box 10, so that the battery 200 is located within the closed receiving cavity 11, thereby protecting the battery 200. Wherein, as Figure 2 and Figure 3 As shown, the lid 20 and the box 10 can be connected via a rotating shaft 21, allowing the lid 20 to be opened or closed by flipping it toward a position away from or near the opening. Of course, as... Figure 4 As shown, the cover 20 can also slide along the first direction of the box 10 to open or close the cover 20. By sliding the cover 20 along the first direction of the box 10 or rotating it around the rotation axis 21, the box 10 can be opened or closed to facilitate the replacement of the battery 200. Compared with the method of fixing the cover plate 0200 to the battery compartment 0100 with bolts 0300, the convenience and efficiency of replacing the battery 200 of the material transfer trolley are improved.

[0036] In some embodiments, such as Figures 2 to 4As shown, the battery compartment 100 can adopt a cuboid structure so that the receiving cavity 11 can adapt to the size requirements of the battery 200. The receiving cavity 11 can be divided into a first compartment and a second compartment by a partition. The first compartment is located close to and electrically connected to the body 300 of the material transfer cart, and can be used to place electronic components. The second compartment can be used to accommodate the battery 200. Metal spring clips can be located on the partition, allowing the battery 200 and electronic components to be electrically connected via the metal spring clips. It should be noted that, as... Figure 4 As shown, the first direction is the length direction of the battery compartment box 100.

[0037] In some embodiments, such as Figures 2 to 4 As shown, the cover 20 may have a fixed end 22 and a movable end 23 arranged opposite to each other. The fixed end 22 of the cover 20 is fixedly connected to the housing 10 by fasteners such as bolts. The movable end 23 of the cover 20 can slide along the first direction of the housing 10 or rotate around the rotation axis 21. That is, a part of the cover 20 is fixedly connected to the housing 10 to protect the electronic components of the battery compartment 100. Furthermore, a part of the cover 20 can be opened and closed to allow replacement of the battery 200 in the receiving cavity 11. It should be noted that the area of ​​the cover 20 that covers the electronic components is smaller than the area of ​​the cover 20 that can be opened and closed, and the area of ​​the cover 20 that can be opened and closed must be larger than the area of ​​the battery 200 to facilitate battery replacement.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the rotating shaft 21 is closer to the fixed end 22 than the movable end 23, meaning the rotating shaft 21 can be located between the movable end 23 and the fixed end 22 of the cover 20, to achieve the effect of partially flipping the cover 20. Preferably, as... Figure 2 and Figure 3 As shown, the rotating shaft 21 can be located on the central axis of the cover 20 along the width direction and close to the fixed end 22 of the cover 20. The cover 20 can achieve a flipping angle of no more than 110°. This allows for partial flipping of the cover 20 to facilitate battery replacement while reducing the volume of the battery compartment 100, which is beneficial for meeting the lightweight requirements of the material transfer trolley.

[0039] In some embodiments, such as Figure 4 As shown, the cover 20 has a limiting end 26, and the limiting end 26 can be disposed between the movable end 23 and the fixed end 22 of the cover 20 to achieve the effect of a portion of the cover 20 sliding along the first direction. Preferably, as shown... Figure 4As shown, the limiting end 26 can be located on the central axis of the cover 20 along the width direction and close to the fixed end 22 of the cover 20, so as to achieve the sliding effect of a part of the cover 20 along the first direction, while reducing the volume of the battery compartment box 100, which is conducive to meeting the lightweight requirements of the material transfer trolley.

[0040] Of course, in the above embodiments, the entire cover 20 can also be flipped or slid. That is, the rotating shaft 21 can be set at the fixed end 22 of the cover 20 so that the entire cover 20 can be flipped around the rotating shaft 21, thereby opening or closing the entire receiving cavity 11. Alternatively, the limiting end 26 can be set at the fixed end 22 of the cover 20 so that the entire cover 20 can slide along the first direction, thereby opening or closing the entire receiving cavity 11.

[0041] like Figures 2 to 4 As shown, in order to facilitate the opening and closing of the cover 20, the movable end 23 of the cover 20 may be provided with a protrusion 24, so that the operator can easily apply a vertical or horizontal force to the protrusion 24 of the cover 20 to open and close the cover 20.

[0042] In some embodiments, such as Figures 2 to 4 As shown, the protrusion 24 can extend from the movable end 23 in a direction away from the fixed end 22. Of course, the protrusion 24 can also be provided on the upper surface of the movable end 23 of the cover 20 and extend in a direction away from the cover 20, so as to facilitate the operator to open and close the cover 20.

[0043] To prevent the cover 20 from opening due to vibration generated during the movement of the material transfer trolley, the movable end 23 of the cover 20 can be connected to the box 10 via a quick-release piece 30. This ensures that the cover 20 can be opened and closed quickly while avoiding vibration, thus facilitating the quick replacement of the battery 200.

[0044] In some embodiments, the quick-release component 30 may include a magnetic element 31, and at least one of the cover 20 and the box 10 may be provided with a magnetic element 31. This means that a magnet or other magnetic element 31 may be provided on the cover 20, or on the box 10. Figure 3 As shown; of course, magnetic components such as magnets 31 can also be provided on both the lid 20 and the box 10 to improve the connection strength between the lid 20 and the box 10. It should be noted that when one of the lid 20 and the box 10 is provided with a magnetic component such as a magnet 31, the other can be made of metal or partially made of metal, so that it can cooperate with the magnetic component 31 to achieve a magnetic attraction effect.

[0045] In some embodiments, the quick-release component 30 may also include a hook and a slot that engages with the hook. One of the cover 20 and the box 10 may have a hook, and the other may have a slot. Specifically, the cover 20 may have a hook, and the box 10 may have a slot that engages with the hook; or the cover 20 may have a slot, and the box 10 may have a hook that engages with the slot. When the cover 20 is flipped closed or slid closed in the first direction, the hook can extend into the slot and abut against the slot wall to prevent vibrations from the material transfer trolley during movement from causing the cover 20 to open. When it is necessary to open the cover 20, the hook can be moved slightly outward from the slot, or the slot can be moved slightly away from the hook to disengage the hook, thus opening the cover 20. It should be noted that the hooks and slots can be made of plastic materials with a certain degree of elasticity, so that the hooks and slots have a certain degree of deformation ability, which can enable the cover 20 to open and close quickly.

[0046] In some embodiments, such as Figure 3 As shown, guide grooves 12 are provided on both sides of the opening of the box body 10, that is, the guide grooves 12 are provided along the length direction of the box body 10. At the same time, guide parts 25 that cooperate with the guide grooves 12 are provided on both sides of the cover body 20. Thus, the cover body 20 and the box body 10 can be accurately closed by the cooperation of the guide parts 25 with the guide grooves 12.

[0047] In some embodiments, such as Figure 3 As shown, the end faces on both sides of the opening of the box body 10 can extend in a direction away from the receiving cavity 11 to form protrusions, and the protrusions fit against the side walls of the receiving cavity 11, so that a guide groove 12 is formed between the protrusions and the outer wall of the box body 10. At the same time, the guide part 25 can be integrated with the cover 20, and the two sides of the cover 20 can be bent to form the guide part 25. When the cover 20 slides in the first direction, the guide part 25 can fit against the side wall of the guide groove 12 and slide along the guide groove 12, ensuring the stability of the sliding of the cover 20 and ensuring the precise closure of the cover 20 and the box body 10; when the cover 20 rotates around the rotation axis 21, the guide part 25 can fit against part of the side wall of the guide groove 12 and flip in a direction away from or closer to the opening, ensuring the stability of the flipping of the cover 20 and achieving the precise closure of the cover 20 and the box body 10.

[0048] The battery compartment 100 for a material transfer trolley disclosed in this application provides a power source for the material transfer trolley by placing the battery 200 in the receiving cavity 11 of the box body 10 and electrically connecting the box body 10 to the vehicle body 300 of the material transfer trolley. Simultaneously, a cover 20 is provided at the opening of the box body 10 to protect the battery 200. The cover 20 can slide along a first direction of the box body 10, or the cover 20 can be connected to the box body 10 via a rotating shaft 21, allowing the cover 20 to rotate around the rotating shaft 21, thereby enabling the box body 10 to be opened or closed.

[0049] The battery compartment 100 for a material transfer trolley disclosed in this application embodiment can be opened or closed by sliding the cover 20 along the first direction of the compartment 10 or rotating it around the rotation axis 21, so as to facilitate the replacement of the battery 200. Compared with the method of fixing the cover to the battery 200 compartment with bolts, the convenience and efficiency of replacing the battery 200 of the material transfer trolley are improved.
